摘要
为实现实景动画拍摄系统,设计了一种基于嵌入式控制器的实体拍摄支架。针对国外拍摄机器人价格超高的问题,设计了低成本、简便易用的实景动画拍摄系统,完成了计算机端插件、通信接口、嵌入式控制器、运动控制支架。经实际应用,3DMAX中虚拟相机姿态导出精度和分辨率达到30 f/s(帧/秒),实体相机旋转方向和速率与虚拟相机保持完全同步,实景动画系统同步虚拟相机和实体相机运动路后能获得准确影视内容合成效果。
To achieve the live-action and virtual shooting system, an entity shooting bracket based on embedded controller is de- signed. In the light of the problem of ultra-high price of shooting robot in foreign countries, a low cost, easy to use live-action and virtual shooting system is designed, the computer end plug, communication interface, embedded controller, motion control support are completed. By practical application, the accuracy and resolution of virtual camera pose reach 30 f/s, the rotation direction and speed of live-action camera remain completely synchronized with the virtual camera. After the live-action and virtual system syn- chronize the motion path of virtual camera and camera, the accurate video content synthesis effect is obtained.
